OPERATION
POWER INDICATOR (Fig. 1)
This Lithium-Ion battery pack is equipped with
a power indicator that displays the battery
pack’s charge status. Press the power-
indicator button to display the LED lights.
The LED lights will stay lit for approximately
4 seconds.
LOW CAPACITY WARNING
If one LED on the power indicator begins to
ash, the battery pack’s charge is under 20%
capacity and should be recharged soon.
Unlike other battery pack types, Lithium-Ion
battery packs deliver fade-free power for their
entire run time. The tool will not experience a
slow, gradual loss of power as you work. To
signal that the battery pack is at the end of its
run time and needs to be charged, power to
the tool will drop quickly.
The power indicator will begin to display
four ashing LED lights when it is completely
discharged. When this happens, remove
the tool from the workpiece and charge the
battery pack as needed.
BATTERY PROTECTION
To protect the battery from damage and
prolong its life, the battery pack circuitry
will turn off the battery pack if it becomes
overloaded or if the temperature becomes too
high during use. This may happen in extremely
high torque, binding and stalling situations.
The battery pack will begin normal operation
when it cools down.
The power indicator will display four ashing
LED lights if the circuitry detects a momentary
overload. You can conveniently reset the
battery pack by releasing the power-tool
trigger. Press the power-indicator button
again to display the remaining charge.
NOTICE: If the power indicator continues to
ash four LED lights after resetting, place
the battery pack on the charger to evaluate
the battery condition.
NOTICE: A signicantly reduced run time
after fully charging the battery pack indicates
that the battery is near the end of its usable
life and must be replaced.

OPERATION
COLD WEATHER OPERATION
When the battery pack is very cold, it may
“pulse” for the rst minute of use to warm
itself. Put the battery pack on a tool and use
the tool in a light application. After about a
minute, the battery pack will have warmed
itself and will operate normally.
WHEN TO CHARGE THE
BATTERY PACK
The Lithium-Ion battery can be charged at
any time and will not develop a “memory”
when charged after only a partial discharge.
It is not necessary to run down the battery
pack charge before recharging. Remove
the battery pack from the tool when it is
convenient for you and your job.
1. Use the power indicator to determine when
you need to recharge the battery pack.
2. You can “top-off” your battery pack’s
charge before starting a big job or long
period of use.
3. Due to Lithium-Ion’s fade-free
properties, the only time it is necessary
to charge the Lithium- Ion battery pack
is when the pack has reached the end of
its charge. To signal the end of charge,
power to the tool will drop quickly.
Charge the battery pack as needed.
